title: Congenital hemangiopericytoma presenting as rectal bleeding in a neonate: a case report.
abstract: Hemangiopericytoma is a rare soft tissue lesion originating from capillary pericytes that can occur anywhere vascular capillaries are found. It is an uncommon tumor found typically in adults but rarely in children. We describe a previously unreported case of an intraluminal lesion in a neonate.
